Java - FontMetrics without Graphics

Question

How to get FontMetrics without use Graphics ? I want to get FontMetrics in constructor, now I do this way:

BufferedImage bi = new BufferedImage(5, 5, Buffer         


        

Answer 1

No you do not necessarily need to get/use the graphics object:

Font font = new Font("Helvetica",Font.PLAIN,12);
Canvas c = new Canvas();
FontMetrics fm = c.getFontMetrics(font);

If you now call c.getGraphics() it will return null. Instead canvas will also work in headless mode.
